Thread: Engine ticking still, After lifter replacement.

"glitter" in the pan you see is most likely copper, from a bearing. It wont be magnetic of course, but if you SEE it in the pan, then that's not good. You have bearing wear, or damage.

This can be some of your problem...low oil pressure or contaminates in the oil can cause bearing damage. You might have toasted a rod bearing, and what you hear is rod knock, meaning the rod has excessive play on the crank, and as you rev. the engine the oil pressure goes up, and the tolerances decreased making the sound quiet down, or go away. When the RPM's go down, the oil pressure does too, and the tolerances increased and the knock comes back.

I think your probably due for either a rebuild if you stop driving it now, or a replacement if you keep on driving it. (replacement meaning engine failure)

the up and down in oil pressure can quiet down rod knock if its not too bad of bearing damage, but low oil pressure can also make lifters chatter like this too, because they dont have enough pressure to pump them up with oil, so you hear them "screaming" because they are thirsty for oil.

The increased gap somewhere, where the bearing is damaged or trashed can cause low oil pressure because its just gushing out a BIGGER opening that hat it should be, and the rest of the engine is starved for the oil it needs.

I would suggest getting a oil pressure tester on the engine, and seeing what you have.

Most everyone with a aftermarket gauge set sees 60PSI almost all the time, others see 60 at a cold start, and as the engine warms up, the pressure drops. So on a cold start it can be 60 at idle, and once warmed up, it can be as low as 22 or 25 PSI. Sometimes its not REALLY that low, as the senders are not that great to go by. Just telling you what the gauge may read, and how it can very from car to car/gauge set to gauge set.
